www.grc.nasa.govGlenn Research Center Cleveland, Ohio 44135 Tensor analysis is the type of subject that can make even the best of students shudder. My own post-graduate instructor in the subject took away much of the fear by speaking of an implicit rhythm in the peculiar notation traditionally used, and helped me to see how this rhythm plays its
ON the EXPANSION of the UNIVERSE - NASA
www.grc.nasa.govgalaxy is obtainable from astronomical measurements, but is not necessarily treated in terms of a higher dimensional geometry3. It is treated, rather, as an abstract numerical measure related to the distance – a type of metric – between P and P*. S and θ, in turn, are related by another “constant of proportionality,” ρ.
